3.6.8 Gyro HWIL Stimulation

The following requirements will be considered as TBC pending Gyro supplier selection. The requirements

given are indicative of the interfaces and necessary functionality to be provided.

Gaia comprises 3 Gyro Packages connected to the SVM 1553 BUS.

Each Gyro package offers redundant rate measurement about a single axis.

For each Gyro package, test inputs are available to allow rate bias to be added to the prime and redundant

output channels when Gyros are HWIL.

AVI-936/GSE-SYS-745/T

For each Gyro package, the Avionics SCOE shall provide 2x (RS422) test interfaces as defined in:

[AD06] Table 3.5-5 (SBL Driver Specification) and Table 3.5-6 (SBL Receiver Specification).

AVI-1052/CREATED/T

In open loop test mode simulated angular rates shall be set at the local MMI or CCS (Test

Procedure/Command Line).

AVI-1053/CREATED/T

In closed loop test mode the RTS shall send the simulated angular rates for all Gyro channels

configured for HWIL operation.

AVI-1891/GSE-SYS-751/T

The Avionics SCOE shall be capable of supporting simultaneous update in closed-loop mode of all 6

Gyro channels.

AVI-2830/CREATED/T

The data message structure to be output on the RS422 to the Gyro units shall be as defined in the

Gyro ICD TBD.
